1. A method for communicating electrical positioning information of an actuator-positioned final control element, said positioning information resulting from continually sensing a position of the final control element, comprising the steps of:

  • forming or receiving a binary signal having a signal condition 0 when the final control element has attained a predefined position or position range, and a signal condition 1 when the final control element has not attained the predefined position or the position range; and

    for forming a positioning signal combining the signal conditions of the binary signal and the continually sensed positioning information such that the signal conditions of the binary signal, the positioning information, or both can be optionally invoked from said positioning signal.
